Abstract: In endoscopy, each of a display controller and a recording controller acquires a first curved shape of an endoscope insertion portion when an endoscope distal end portion is located at a predetermined site, an endoscopic image captured in the endoscopy, and a second shape of an endoscope insertion portion when the endoscopic image is captured. The recording controller may record the first curved shape of the endoscope insertion portion, the endoscopic image, and the second curved shape of the endoscope insertion portion in a storage device. The display controller may simultaneously display the first curved shape of the endoscope insertion portion and the second curved shape of the endoscope insertion portion on a display device.

Abstract: An examination time period evaluator acquires a time evaluation index related to a predetermined examination step (e.g. a net observation step) in an endoscopic examination. An image classifier acquires an implementation record of the endoscopic examination. An examination time period classifier calculates an actual time, i.e. a time required for the predetermined examination step, based on the implementation record. A display controller may display the evaluation index and the actual time on a display apparatus. The display controller may further display a comparison result between the evaluation index and the actual time on the display apparatus.
